Overall, zPLATFORM and Zettabyte are designed for sovereign-grade deployments, where data isolation, auditability, and operational control are mandatory, not optional.

zWARE functions like the advanced electrical systems of a high-performance race car, delivering essential real time data to allow the driver to make the best decisions. Without this visibility, even the most skilled driver cannot perform optimally. In the same way, AIDC operators controlling multi-million-dollar GPU clusters need zWARE to see, respond, and optimize in real time.

zWARE is not merely an AI scheduler, it is a comprehensive, converged control plane for GPU centric AI infrastructure. It extends well beyond job scheduling to operate as a full AI Digital Command Center integrating orchestration, observability, and operational control across the entire AI stack. zWARE incorporates ultra fine grain to include adjacent telemetry spanning compute, networking, power, cooling, and environmental signals. ZWARE also supports multi-cluster federation across heterogeneous GPU domains; performs intelligent workload-to-hardware matching based on real-time system state; and delivers continuous operator alerting and feedback loops. zWARE is designed for sovereign-grade deployments, where data isolation, auditability, and operational reliability are mandatory, not optional.

zWARE is designed for anyone that operates GPU based AI infrastructure. This includes sovereigns, enterprises, data center operators, telecos, research institutions, and AI focused companies running training, fine tuning, or large-scale inference workloads. It is suited for on-premises and multisite environments where control, efficiency, and operational reliability are required.

zWARE integrates directly with existing hardware and networking environments, without changing GPU ownership or data control. GPU owners can adopt zWARE in three ways: by deploying it on existing bare-metal or virtualized GPU clusters; by bundling it with new GPU infrastructure through Zettabyte’s OEM partners; or by operating it as a managed service supported by Zettabyte’s AI Network Operations Center. This flexibility allows organizations to bring systems online quickly while maintaining control and operational continuity.

zWARE includes Zettabyte’s own optimized Kubernetes. It incorporates: (1) an optimized Kubernetes distribution hardened and tuned for GPU intensive AI workloads; (2) a custom, AI-aware scheduler and orchestrator that operates beyond native Kubernetes abstractions; and (3) GPU-level resource awareness with fine-grained control over allocation, performance states, and operational constraints. Together, these capabilities allow zWARE to operate large-scale, high density GPU clusters, enabling deterministic workload placement, sustained performance, and reliable operations in environments where standard container orchestration alone is insufficient.

zWARE increases effective GPU utilization by ensuring that available compute is used consistently and predictably. By reducing idle capacity, avoiding fragmentation, and responding quickly to operational issues, zWARE enables more tokens to be produced from the same infrastructure. Customers typically achieve 30–40% higher effective GPU utilization, allowing them to deliver results faster while lowering the cost per training run or inference job.

zWARE is designed for organizations that need to operate AI infrastructure on their own terms. Unlike hyperscaler platforms, it preserves GPU and data ownership while providing full visibility and control across the infrastructure. Compared to open-source stacks, zWARE is production ready by design, delivering consistent performance, integrated operations, and measurable improvements in GPU utilization and throughput. This allows teams to run AI workloads more efficiently, scale with confidence, and reduce the long-term cost of operating high-density GPU environments. zWARE also allows on-premise deployments to scale and obtain additional capacity or resources through the zSUITE ecosystem.

Currently, there are two primary types of liquid cooling solutions being deployed.

• Direct to Chip Cooling (Direct Liquid Cooling): This technique involves taking coolant directly to the source by attaching cold plates to heat generating chips. These cold plates connect to coolant-filled tubes that extract the heat from the chips. 
• Liquid to Rack Cooling: Coils containing chilled water are placed in the rear of the cabinet. These coils connect to the chilled water loop that runs through the facility, absorbing heat and transporting it out of the cabinet.

When implementing liquid cooling, several considerations must be taken into account to ensure proper roll out, including pump and flow rate to maintain consistent circulation across variable workloads without frequent maintenance, heat exchanger capacity to ensure it is able to handle the thermal load of the system, and leak detection and prevention systems to ensure immediate detection of potential problems through advanced sensors and high quality seals and fittings. Zettabyte with its proven track record of successful deployments helps customers design, install, and maintain liquid cooling systems tailored to their customers' needs derisking this critical deployment while also providing neutral sourcing and unmatched procurement speed.

There are several benefits to deploying a liquid cooling solution, including i) noise reduction compared to air cooled solutions, ii) a smaller system footprint due to the removal of the fans, iii) increased reliability and performance, and iv) most importantly it enables the data center to support high density computing options, which air cooling cannot do.

Zettabyte’s strategic partners and investors produce 60+% of the world’s data center equipment. With this forward looking knowledge ZETTABYTE advises customers on the best cooling system for them considering both the current thermal needs of the existing equipment deployed and the higher cooling requirements needed for future growth and HPC workloads.

A coolant temperature rise between 7.5°C and 12°C is recommended. A common design target is a 10°C differential, which balances heat exchanger efficiency and pump workload, optimizing for a flow rate-to-heat dissipation ratio of approximately 1.5 LPM/kW.

An N+1 redundancy model is the standard. This means for 'N' required CDUs to handle the operational load, one additional backup CDU is installed per row. This ensures seamless failover without service interruption if a primary unit fails.

Floor drains should be sized based on the maximum potential flow rate of a leak. For high-density racks, this means a capacity of at least 200-400 L/min (approx. 50-100 GPM) to rapidly remove coolant and prevent pooling during a major line breach.

Manifolds should be isolated and pressure-tested on-site at 1.5 times the maximum operating pressure (MAOP) using an inert gas like dry nitrogen. The pressure should be held for a minimum of 30-60 minutes to check for any drops, which would indicate a leak. Zettabyte’s TITAN, a next generation AI Data Center (AIDC) initiative designed to transform the availability, scalability, and efficiency of GPU-based computing worldwide, embeds these controls into its data hall designs and acceptance processes.  

The maximum acceptable vibration level for pumps and adjacent piping should not exceed 0.3 g RMS (root mean square). Vibration monitoring should be implemented to detect and address any excursion beyond this threshold to prevent long-term fatigue on fittings.

A minimum separation of 50 mm (approximately 2 inches) should be maintained between liquid cooling lines and high-voltage power cables. If this is not possible, EMI shielding (e.g., metallic conduit or raceways) must be used to prevent electromagnetic interference.

A sustained drop in flow rate of 10-15% below the established baseline for the given heat load is a critical early indicator of pump degradation or a blockage. This should trigger an alert for investigation well before temperature alarms are activated.

Temporary or portable cooling units can be used, or a bypass loop with quick-disconnect fittings can be implemented. This allows maintenance teams to isolate a section of the primary cooling system while maintaining coolant flow to the critical IT load, ensuring zero downtime.

The fastest method to isolate a leaking cooling line without shutting down adjacent racks is to use quarter-turn shut-off valves installed at the inlet and outlet of each rack's manifold. This allows technicians to immediately isolate a single rack from the main cooling loop in under a minute without affecting adjacent equipment.  Zettabyte’s experience delivering high-density, liquid-cooled AI infrastructure helps     customers reduce risk by ensuring cooling systems are designed for routine     maintenance and component replacement, allowing issues to be resolved quickly without broader impact to cluster operations.

An N+1 or 2N redundant pump configuration within the CDU is essential. Upon a primary pump failure, a backup pump automatically starts, maintaining coolant flow and pressure with no interruption to cooling delivery.

Leak detection ropes/cables are placed at the bottom of each rack and along coolant piping paths. These leak detection ropes/cables are connected to a monitoring system that triggers an alarm and can automatically shut off coolant flow to the affected zone. Zettabyte with its proven track record of successful deployments helps customers design, install, and maintain liquid cooling systems tailored to their customers' needs derisking this critical deployment.  

Coolant quality is maintained through continuous water treatment, including particle filters, UV sterilizers, and the use of pre-mixed, industry-approved coolants with specific anti-corrosion and biocide additives. Regular testing is required to verify coolant chemistry and detect degradation over time.

The optimal supply pressure is typically between 1.5 and 2.5 bar (approx. 22-36 PSI). This range is high enough to ensure adequate flow through the complex microchannels of the cold plates but low enough to minimize long-term stress on seals and fittings.

The minimum recommended width for a cold aisle is 1.2 meters (approx. 4 feet). For high-density racks requiring frequent access or simultaneous servicing, a width of 1.5 to 1.8 meters (5-6 feet) is preferable to ensure safety and efficiency.

The floor must be rated for a minimum of 2,500 kg (approx. 5,500 lbs) per rack footprint. A structural engineer must certify the point load capacity of the raised floor pedestals and tiles to prevent structural failure.

A minimum of 1.2 meters (4 feet) of separation between rows is recommended. In hot aisle/cold aisle containment setups, this ensures that exhaust heat from one row does not recirculate into the cold air intake of an adjacent row.

A data center-rated server lift with a minimum capacity of 500 kg (1,100 lbs) is required. This data center rated server lift provides a stable platform and precise height adjustment to safely install or remove heavy servers without risking injury or equipment damage.

Installation should follow a "center-out" or "end-to-end" sequence, establishing main access aisles first. Protective coverings should be used on installed racks, and clear, temporary pathways must be maintained for moving equipment and personnel.

Replacement is performed using drip-free quick-disconnect couplings. The typical approach is to: 1) Isolate the server electrically. 2) Close shut-off valves on the manifold for that server's loop. 3) Disconnect the quick-disconnect couplings. 4) Un-rack the failed server and replace it. 5) Reconnect and open valves. Zettabyte’s experience delivering high-density, liquid-cooled AI infrastructure helps customers reduce risk by ensuring cooling systems are designed for routine maintenance and component replacement, allowing issues to be resolved quickly without broader impact to cluster operations.

The maximum extraction force should not exceed 500 Newtons (approx. 112 lbf). If a server is stuck, technicians should check for obstructions or binding in the rails rather than applying excessive force that could damage the rack frame.

A best practice is to reserve 5-10% of rack space as "hot spares". This provides empty, pre-cabled, and pre-plumbed slots to quickly relocate a workload or replace a failed server chassis without waiting for repairs.

Yes, when properly designed and installed, the floor system and power distribution can safely support a rack with a 250 kW load and an installed weight exceeding 800 kg during seismic events. The entire installation, including the floor, rack anchoring, and overhead power/cooling distribution, must be certified by a structural engineer to withstand the specified seismic load (e.g., 0.3g) for the total weight of the fully-loaded rack. Zettabyte with its battle tested approach builds future-proof, supply chain neutral AI data centers for Sovereigns and enterprises around the world.

Replacement of a failed liquid-cooled server is typically performed by a trained two-person team following a documented procedure. The process includes 1) verification of correct server, 2) closing the isolation valves serving the affected cooling loop, 3) disconnecting the quick-disconnect couplings in a controlled manner, 4) using absorbent pads to manage any residual coolant drips, 5) removing and replacing the server, 6) reconnecting the cooling interfaces securely, and 7) gradually reopening the isolation valves to restore coolant flow.

Seals and O-rings on quick-disconnects should be inspected visually during every server maintenance event and undergo a full replacement every 2-3 years or as specified by the manufacturer to prevent material degradation and ensure a reliable seal.

Cable trays and pathways should be designed with a 50% "day one" fill rate. This provides capacity for future growth and ensures adequate space to maintain proper cable bend radius and airflow.

A single-tier (leaf-only) or two-tier (leaf-spine) architecture is optimal. For up to ~64 nodes, a single tier of high-radix switches can provide all-to-all connectivity. Beyond that, a two-tier design minimizes hops and maintains low latency. In Zettabyte deployments, network topology decisions are guided by workload scale, communication patterns, and growth expectations. zFABRIC, Zettabyte’s high performance RDMA networking solution, implements these architectures using vendor-agnostic, high-performance fabrics that maintain low latency as clusters expand, allowing teams to scale training environments without re-architecting the network or introducing unnecessary latency overhead.

A 1:1 or 1:2 non-blocking or low-oversubscription ratio is optimal for AI/ML. For InfiniBand, this means the number of uplink ports from leaf switches to spine switches should be equal to or half the number of downlinks to servers.

High cable densities are managed through the use of horizontal and vertical cable managers with rounded edges. Cable routing is designed to maintain a minimum bend radius of four to eight times the cable’s outer diameter, with planned pathways that avoid sharp turns, compression, or pinching along the route.

Misconnection risk is reduced through the use of unique, machine readable labels such as QR codes or barcodes, applied at both ends of every cable. Each label encodes source and destination information (for example, rack, server, and port) and is linked to a centralized reference database to support verification during installation and troubleshooting.

Cable integrity is validated by testing and certifying every high speed cable, particularly DACs and AOCs, using a network cable analyzer (for example, a Fluke DSX CableAnalyzer) prior to installation. Testing verifies key performance metrics such as insertion loss and return loss to confirm the cable meets required specifications before it is connected to production equipment.

In large scale InfiniBand environments, failed cables are identified using network management software with port-mapping capabilities that correlates switch port status to the physical cable infrastructure database. When a link fails, the system instantly identifies the exact cable and its physical location. In Zettabyte deployments, this correlation is implemented through fabric-aware tooling that maintains alignment between switch ports, cabling layouts, and rack topology. By preserving this mapping as part of day-one design and ongoing operations, failures can be isolated rapidly even at multi-thousand-port scale, reducing mean time to repair and minimizing disruption to distributed training workloads.

Rolling maintenance is enabled through the use of redundant network fabrics, such as dual-rail architectures. Maintenance activities are carried out on one fabric while traffic is failed over to the alternate fabric. This approach relies on network protocols and workload schedulers that support graceful failover to maintain job continuity during maintenance operations.

A service loop of approximately 0.5 to 1 meter is maintained for all cables connected to servers. This provides sufficient slack to slide a server out for servicing or reposition it into a spare slot without requiring cable disconnection or re-routing.

Fault tolerance is achieved through a dual-fabric (or “dual-rail”) network architecture. Each server is connected to two fully independent network fabrics, allowing traffic to automatically reroute through the alternate fabric if a component in one fabric fails. In Zettabyte deployments, this architecture is implemented and operated using zFABRIC, which is designed to keep AI systems productive even when underlying components fail. Through automated failover, continuous link health monitoring, intelligent rerouting, and rapid recovery, zFABRIC minimizes disruption to training and inference workloads. This reduces GPU hang time, protects delivery timelines, and allows operators to meet SLA expectations minimizing manual intervention, resulting in more predictable operations and fewer costly interruptions.

Traditional network monitoring tools such as SNMP provide useful baseline health and status information, but lack the real-time granularity required to detect transient congestion and error conditions in high-performance GPU interconnects. In Zettabyte deployments, In-band network telemetry (INT) and hardware-level counters from the switches and NICs are used. Zettabyte also incorporates ultra fine grain to include adjacent telemetry spanning compute, networking, power, cooling, and environmental signals. This provides real-time, granular data on packet buffers, latency, and congestion points, which is fed into a central monitoring platform giving sovereigns and enterprises full ownership, and complete operational independence.

Circuit breakers with high inrush tolerance—such as Type C or Type D—are used and sized at approximately 125% of the server’s maximum continuous load. The high-inrush characteristic accommodates brief startup current surges during power-on, while the breaker sizing continues to provide protection against sustained overcurrent conditions.

A minimum of two (A/B) independent power feeds from separate Power Distribution Units (PDUs) is required for each rack. Each feed should connect to one of the redundant Power Supply Units (PSUs) in each server, allowing continued operation if a single feed or distribution path is lost.

A UPS runtime of approximately 5–10 minutes at full load is typically provisioned. This interval provides sufficient buffer time for backup generators to start, stabilize, and assume the load, while accommodating potential start-up or synchronization delays during the transfer process.

Power quality is verified by conducting a power quality audit using a power quality analyzer prior to energizing the servers. The audit measures voltage, current, harmonic distortion (THD), and transient conditions over a defined period to confirm that the supplied power is clean and stable.

Safety verification is performed through on-site testing that includes insulation resistance (megger) testing, continuity checks, and torque verification of all electrical connections prior to energizing the panel. These tests confirm the absence of faults and ensure that all connections are properly secured.

A minimum of 20% spare breaker capacity should be reserved within electrical panels. This margin allows for future expansion or emergency circuit additions without requiring major shutdowns or panel replacement.

Outlet-level power monitoring on the rack PDUs is required. In Zettabyte deployments, zWARE ingests this real time power data and correlates it with adjacent telemetry across compute, networking, cooling, and environmental signals. zWARE’s fine grained visibility allows emerging faults to be identified early, enabling operators to intervene before issues escalate. Overall, zWARE and Zettabyte are designed for sovereign-grade deployments, where data isolation, auditability, and operational control are mandatory, not optional.

For large loads during peak training periods, it is important to balance the power draw through the use of automated transfer switches (ATS) and intelligent PDUs that monitor power conditions across phases and utility feeds. Zettabyte’s zWARE improves utilization with smart scheduling, dynamic load balancing, and power/cooling integration acting like the electrical system of a high performance race car giving owners complete control and ownership.

Power systems are typically designed to limit voltage sag to no more than approximately 8% of nominal voltage during large GPU job startups. This ensures that sudden current inrush from high-density GPU clusters does not disrupt system stability or impact ongoing operations.

A fully redundant 2N power architecture is required. This means two independent utility feeds, generators, UPS systems, and distribution paths all the way to the rack, ensuring that the failure of any single component does not cause an outage.

The backup power strategy follows a UPS-to-generator handoff model. The UPS provides immediate, uninterruptible power upon utility loss, while generators are signaled to start. The generators are required to accept the full 4 MW load within the available UPS runtime, which is typically designed to be 5–15 minutes.

An on-site "hot spare" inventory of critical components is maintained. The inventory level is based on component failure rates (MTBF) and vendor lead times to ensure that any critical part can be replaced within the 4-hour Mean Time To Repair (MTTR) target. In Zettabyte deployments, sovereigns and enterprises benefit with a truly supply-chain-neutral AI data center model and unmatched procurement speed eliminating costly delays and lowering customers Total Cost of Ownership.

Integrated Systems Testing (IST) at full load should be performed before go-live. Contingency planning involves securing on-site spares for critical long-lead-time components (e.g., pumps, chillers, high-capacity breakers) and pre-qualifying alternative vendors. Zettabyte embeds these practices directly into data hall designs, commissioning plans, and SLAs, allowing operators to identify issues early, shorten deployment timelines, and bring AI capacity online with greater certainty and lower operational risk.

Yes, a Data Center Infrastructure Management (DCIM) system should be integrated with the workload scheduler. This allows the scheduler to place jobs based on real-time power and cooling availability in specific racks, preventing overloads. Zettabyte’s AI DCIM and command center gives customers precise operational control of their GPU estate across power, cooling, networking, and workload health, so capacity stays predictable and issues are isolated before they cascade. Zettabyte’s platform turns build specifications, rack topology, and thermal limits into clear, actionable runbooks, and keeps mixed GPU vendors and generations running as one governed fleet without forced upgrades.  

A resilient scheduling policy should be applied. In Zettabyte environments, zWARE, a full AI Digital Command Center integrating orchestration, observability, and operational control across the entire AI stack, is deployed. zWARE incorporates ultra fine grain monitoring, multi-cluster federation across heterogeneous GPU domains, and performs intelligent workload-to-hardware matching based on real-time system state delivering continuous operator alerting and feedback loops. This allows critical jobs to be configured with frequent checkpointing to preserve progress. If a node fails, the scheduler attempts to restart the job from the most recent checkpoint on an available spare node. When no spare capacity is available, the job is queued and rescheduled based on its assigned priority.
